loose L1A1 hinge pin

I'm not sure if this is a common problem or not but I have an L1A1 with a hinge pin that is constantly coming loose and I can't figure out a way to tighten it down. Any suggestions?

shorten the female end so it is just a hair below flush. You can do this on semiautos as there is no risk of pinching the non-existent safety sear.

Splay the ends of the fork. The hinge is not meant to clamp the upper and lower together

Because doing so would pinch the safety sear. Without a safety sear, making the female end shorter WILL clamp the upper and lower together. Which is not adverse to accuracy.

This has always worked the best for me also, with perceived accuracy benefits to boot.
